Why is the test paper always weak positive after ovulation?

Ovulation test strips have many applications in life. They are generally used when preparing for pregnancy. They are mainly used to detect the level of luteinizing hormone in women to determine whether ovulation has occurred. However, there will be some problems. The most common one is that the test paper is always weakly positive after ovulation. Only by finding out the reason can you avoid more trouble. So, what is the reason why the test paper always shows weak positive after ovulation? Let’s take a closer look at it below.

Ovulation test strips predict ovulation by detecting the peak level of luteinizing hormone (LH).

Normal women maintain a small amount of luteinizing hormone (LH) in their bodies, and the secretion of LH increases rapidly in the middle of the menstrual cycle.

The hormone LH increases with the passage of time, forming an LH surge, and within the next 28 hours, stimulates the release of a mature egg, i.e. ovulation.

Within 24 to 48 hours before female ovulation, the luteinizing hormone (LH) in urine will reach a peak value, and the result will be positive if the ovulation test strip is used for self-test. The specific test method is generally described on the packaging of the ovulation test strip (it must be done strictly in accordance with the instructions to minimize the error). Unlike early pregnancy test strips, morning urine cannot be used, and urine samples at the same time of day should be used as much as possible. Water intake should be reduced 2 hours before urine collection, because diluted urine samples will also hinder the detection of LH peak. If the menstrual cycle is relatively regular, the test is carried out for six consecutive days, 14 days before the menstrual period (that is, the expected ovulation time), the first three days of this time plus the last three days; if the menstrual period is irregular or abnormal, the test is generally started on the third day after the menstrual period is over. Although the test strip is easy to use, due to the production process, the operator itself and other reasons, the accuracy rate is only about 75%.

A weak positive result on the ovulation test paper means that a woman always gets a weak positive result when using the ovulation test paper during her ovulation period, and no strong positive result is seen. There is a layer of chemical on the ovulation test paper. The amount of chemical applied on each brand of test paper is certain. When the LH in the woman's urine on the ovulation day is less than the amount applied on the test paper, no strong positive result will be detected. Usually in this case it is not that there is something wrong with the woman's body, but that the test strip is not suitable for her. If you find that the test paper is always weakly positive, you can use the Mami Pregnancy Tester to test ovulation. As long as ovulation is normal, the ovulation day can be detected.

The above is an introduction to why the test paper always shows a weak positive result after ovulation. I hope it will be helpful for women to understand. Because different ovulation test strips contain different levels of chemical reagents, when the LH in a woman's urine is less than the amount applied, this situation will occur. At this time, it is also a good idea to change the type of test strip in time. As long as ovulation is normal, accurate predictions can be made.
